MH stickers

Can anyone tell me what the black silhouette stickers on the back of motorhomes mean?
Weve guessed it could symbolize where the owners have been or something like that , but haven't a clue. :Blush:
We have seen stags , mosquito's ,moose and a scorpion , we think . There is usually just 1 on each mh , but we saw one with several on last week in Scarborough .
Can anyone enlighten me ?
Thanks

Doesn't anyone know. They aren't that big maybe 6 inch or so. We have seen them all over the place , not just in Yorkshire.
Has nobody else ever noticed them?
Surely it must stand for something , or why bother ?

I have the catalan donkey (cataluna,spain), the bull comes in black and now silver and although they are bought as a momento of spain, it actually started life advertising their brandy throughout spain
